Description
Technical field
The invention belongs to oil-gas field surface engineering and chemical industry environmental technology field, particularly a kind of biological assist type is pneumatic breaks and three-phase vacuum draw soil restoring device and method.
Background technology
In the past few decades, be subject to the restriction of the many factors such as period of history economic technology condition and people's level of understanding, oil play, when making major contribution for country, has also brought a series of environmental problem: the pollutants such as the waste water in oil-gas mining process, waste gas, ground crude oil, waste gas drilling fluid enter environment and can impact water body, atmosphere, soil and ecological environment.Along with the extensive use of petroleum resources, the oil pollution in environment is more and more serious.In Petroleum Production, storing, refining processing and use procedure, also have overflowing and discharging of petroleum hydrocarbon, cause water body and the serious oil pollution of soil around of oil field and petrochemical factory.In the world today, the total output of oil approximately has 2,200,000,000 t every year, and wherein 17.5 hundred million t are by land field produces.The whole world has 8,000,000 t entered environments every year, and China has nearly 600,000 t entered environments every year, contaminated soil, underground water, river and ocean, annual new pollution soil 1 * 10
5t.
Since the eighties in 20th century, the oil pollution problem of soil becomes the environmental problem of countries in the world common concern.Because pollutant kind is many, harm is large, reparation behavior cost is high, the time long and invisibility and the complexity of underground situation, the reparation of petroleum-type contaminated soil and the underground water difficult problem that become international.In general, early stage method of administering oil-polluted soils is mainly traditional physics (steaming process, degassing method, organic solvent method, hydrodynamic cleaning method) and chemical method (oxidizing process, heat treating process), these method required times are short, instant effect, but there is the drawbacks such as secondary pollution, disposal cost height, be unfavorable for applying widely.Along with people are to the going deep into of the dynamic purification capability study of soil ecosystem self, produced the biological new technology of intervening soil ecosystem purifying contaminated ability of using artificial.Add biosurfactant or three strains producing biosurfactants can significantly shorten repair time, improve remediation efficiency, and can keep good environment friendly.It with its exclusive contaminant degradation thoroughly, do not cause secondary pollution, operation is simple and whole cost is low, the repair process mode of applicable dissimilar (original position/dystopy) and can simultaneously recover the ecosystem advantage such as beautify the environment, and becomes improvement technology up-to-date, with fastest developing speed.Up to the present, by bioremediation technology, improve oil-polluted soils, being considered to has vitality most, the most representative technology, and as a kind of environmental friendliness technology, oneself becomes the focus of international scientific research for it.
From repair mode, to being subject to the reparation of the soil and groundwater of petroleum-type contaminants to be divided into showering and original position is repaired.Showering is contaminated soil and underground water to be transferred to ground process above, comprises in-situ processing, composting processing, pyrolysis processing, Soil leaching, bioreactor etc.Original position reparation refers to process in the original position of contaminated soil, underground water, comprises biology in situ reparation and in-situ chemical reparation etc.Original position is repaired because of its expense relatively low, and the advantage such as little to environmental perturbation, secondary pollution is little becomes the research and practice main flow of underground water recovery technique.
In soil remediation, water-soluble is the key factor that affects pollutant removal, and a lot of pollutants are all the materials that hydrophobicity is very strong, and it is slow that speed is repaired in general washing, and efficiency is low; People are by adding various additives to strengthen repairing effect in recent years, and these additives can shorten the time, improve pollutants removal rate, and additive must be hypotoxicity and biodegradable.Biosurfactant is a kind of additive of great use, and itself comprises hydrophobic group and hydrophilic radical, can promote dispersion and the solubilising of pollutant on soil particle, but also has nothing or the advantage affecting compared with circlet border and the possibility of growth in situ.
